How to hide a photo behind another photo
I have seen this on different apps, so I am trying to figure it out
iPhone 12, iOS 17
What do you mean by hiding? Are you asking about the illusion, where we can see two different faces in the same image? For example, like here? https://www.csmonitor.com/Science/Science-Notebook/2015/0403/Einstein-or-Marilyn-How-this-optical-illusion-hides-two-faces-in-one-portrait
Depending on how far we are closing our eyes, we can see either Albert Einstein or Marilyn Monroe.
